My HBN experience and process

[asd9055]

Just another followup if I may. In the youtube video he heats up the bullets to 200F before tunmling with HBN. The bullets he was using were OTM. Will A-Max, Accubonds or other similar tipped bullets be OK in the oven? No deformation heating them up to 200F and then putting them in the tumbler?

Again, thanks in advance. My HBN will be here Monday evening.

Should be fine, I've done it at around 200 as well. You know for sure the eld m and x bullets will survive…the heat shield tip!

The way I put it in the original post…160-170 Fahrenheit is the right temperature for a proper latte or cappuccino…if it won't burn a precious hipster's lips your bullets will be just fine

170f would work well enough I'd think,

On another post the guy wasn't even using any artificial heat, just tumbled them outside in the sun (to be fair he was either in Texas or Arizona, so that might be hotter than this haha)

Thank you!
I'll start with some 338 for LM for now. It's one rifle I have no load developed

Hi, first time here.
Found this this morning

And was a little skeptical and started searching and found this thread and so glad I did.

Thank you all, and specially @Calvin45 for this wonderful writing

Adding, the user claims it improves MV something that was discussed here ad nauseum and apparently reduces it.
Claimed they are selling this to the government, I mean we know the government will purchase anything

There are no studies published, so I do have my doubts, a splitted in half barrel photo really doesn't tell much.

But maybe they do have a process that provides benefits, we'll see, many on Reddit will be paying $50 to treat their barrels and I'm sure someone will post velocity measurements

Just wanted to share here

Welcome aboard. I enjoy the heck out of the site/forums too, great sites/forums are due to great contributors. They're here in spades.

Soooo - thanks for bring this post back to the top, I want to start using HBN as well so I just ordered some. I have the same tumbler as asbn9055 shows in post #82 from Harbor Frieght - have been using it for about 7 years without issue but don't want to mess up or contaminate the insides. I like the idea of using a plastic bottle held stationary with a block of wood as Jeff shows in his YT video that Calvin45 linked to in post #1 - keeps the tumbler itself clean and gets those bullets working with the media. Brilliant!

I want to chase every tweak I can to improve my 257 Roberts AI performance for long range coyote hunting - out to 900 - 1000 yards if I can get the performance up in it's current mechanical/physical configuration. Hoping HBN give me more consistent groups and cold bore shots. Some extra velocity would be welcome too.

Hope this thread stays active, I'll certainly contribute my experiences when I get there.

This is very interesting

I doubt it as well.
I think bullets would just fall out of that barrel before reaching the muzzle..
